Le Chatelier’s Principle
The position of equilibrium shifts to oppose any change affecting equilibrium.
Changes in concentration or amounts
Altering the concentration of substances at equilibrium leads to a shift to oppose the change.
Pressure Increased
Equilibrium shifts to the side with fewer moles to counteract the pressure increase.
Pressure Decreased
Equilibrium shifts to the side with more moles to counteract the pressure decrease.
Changes in Temperature
Temperature decrease shifts equilibrium to oppose the change, based on the reaction's endothermic or exothermic nature.
Catalysts
Substances that speed up reactions by providing an alternative pathway with lower activation energy.
Haber Process
Conditions for highest ammonia yield include specific pressure and temperature requirements.
